QUEST with Dave Liebman, Richie Beirach, Ron McClure, and Billy Hart. Founded in 1981, Quest was Billy's bid to move the 1970's evolutions forward. Featuring the remarkable tenor saxophonist/flautist Dave Liebman (like Billy, a Miles Davis veteran), rolling-and-tumbling pianist Richie Beirach, and muscular bass master Ron McClure, Quest (which recorded a dozen albums) is a quartet that breathes and cascades, capturing the rhythms of forests and the flow of mighty rivers. ENCHANCE: Revisited with Billy Hart, Craig Taborn, Dave Holland, Joshua Redman, Oliver Lake, and Eddie Henderson. The band Enchance released a landmark album of the same name in 1977. A look at some of the musicians who played on this explosive record gives an idea of its significance. Master bassist Dave Holland brought in the legacy of Miles Davis, whirlwind pianist Don Pullen came off a long tenure with Charles Mingus, astringent saxophonist Dewey Redman had been the tenor foil for alto saxophonist Ornette Coleman. Enchance captured the ferment and excitement of a neglected period in jazz, when the breakthroughs of the 1960s (engineered by many of the people on the record) were leading to new creative possibilities.
